Seasonal Evolution of Titan's Stratosphere Near the Poles
Flasar, F. M.; Lavvas, P.; Coustenis, A. +5 more
In this Letter, we report the monitoring of seasonal evolution near Titan’s poles. We find Titan’s south pole to exhibit since 2010 a strong temperature decrease and a dramatic enhancement of several trace species such as complex hydrocarbons and nitriles (HC3N and C6H6 in particular) previously only observed at hi…
Reconnection Acceleration in Saturn’s Dayside Magnetodisk: A Multicase Study with Cassini
Coates, A. J.; Krupp, N.; Dougherty, M. K. +16 more
Recently, rotationally driven magnetic reconnection was first discovered in Saturn’s dayside magnetosphere. This newly confirmed process could potentially drive bursty phenomena at Saturn, i.e., pulsating energetic particles and auroral emissions. Using Cassini’s measurements of magnetic fields and charged particles, we investigate particle accele…
Particles Co-orbital to Janus and to Epimetheus: A Firefly Planetary Ring
Sfair, Rafael; Winter, Othon C.; Souza, Alexandre P. S. +3 more
The Cassini spacecraft found a new and unique ring that shares the trajectory of Janus and Epimetheus, co-orbital satellites of Saturn. Performing image analysis, we found this to be a continuous ring. Its width is between 30% and 50% larger than previously announced. We also verified that the ring behaves like a firefly. It can only be seen from …
